Rhythm Tengoku
The GBA original that started the series.

Japan-only — never officially localized.
Overview
Rhythm Tengoku is the game that started everything. It launched on the Game Boy Advance in Japan on August 3, 2006, and it never got an official release anywhere else. It was also the last first-party game Nintendo made for the GBA, which makes it a bit of a send-off for the console. The idea came from musician Tsunku, who pitched a rhythm game to Nintendo built around feeling the beat instead of watching the screen. A Sega arcade version followed on September 20, 2007, also Japan-only.
Gameplay
You play short rhythm minigames using simple button taps timed to the music. The trick is that the music is the guide, not the visuals. Rhythm Tengoku has eight sets of six rhythm games each, and the last three sets are harder reworks of earlier ones. This is also where Karate Man (Karateka) first showed up — it has been a series staple ever since, with a version in every game that followed.
What's New
Everything was new here, since this is the first game. It set the template the whole series still runs on: tiny rhythm games, audio-first timing, a goofy art style, and a soundtrack that does the heavy lifting. There was no localization, so outside Japan most players only know it through fan translations.
Reception
Critics in Japan and importers gave it generally positive reviews — Eurogamer scored it 8/10 and Nintendo World Report 8.5/10. There is no Metacritic page because the game never released in the West. It won an Excellence Prize for Entertainment at the 10th Japan Media Arts Festival in 2006. Lifetime sales were never confirmed.
